Embodiment Construction

[0020] The implementation of the closed structure system of the large-span two-way arch truss cable-membrane structure stockyard includes the following steps:

[0021] Step 1: Establish a calculation model of the two-way arch truss cable-membrane structure, and conduct structural analysis to determine the tensile stress of the prestressed cable, which is used for tensioning the prestressed cable of the two-way arch truss cable-membrane structure.

[0022] Step 2, divide the entire arch space structure into two near-support areas 13 and a top area 14: the main arch truss section 2.2 in the near-support area and the secondary truss connected between the main arch truss sections 1.2 in the near-support area 4 is divided into the area near the support 13, and the main arch truss section 2.1 in the top area and the secondary truss 4 connected between the main arch truss sections 2.1 in the top area are divided into the top area 14.

[0023] Step 3: Construction of the first tempora...

Abstract

The invention discloses a large-span bidirectional arch truss cable membrane material field closed structure system, belongs to the field of large-span space structures, and is particularly suitable for material field closed buildings and the like. The novel bidirectional arch truss cable membrane material field closed structure is mainly composed of an arch gable wall, a middle three-core circular arch truss and an outer cable membrane enclosing structure which are connected with concave secondary trusses. According to the structure, the use characteristics of a material field closed buildingare combined, and a tensioned membrane structure is utilized to act as a building enclosure, so that the consumption of steel is greatly reduced, the engineering cost is effectively reduced, the economical efficiency of the structure is improved, the construction cost pressure faced by large-span material field closed building construction is relieved, and the application prospect is wide. The large-span bidirectional arch truss cable membrane structure system has the advantages of being novel in structural form, reasonable in structure stress, strong in collapse resistance, attractive in architectural image and the like, is convenient to manufacture and install, and has strong practical significance.

Description

technical field [0001] The patent of the present invention relates to the field of large-span cable-membrane roof structures, and specifically relates to a large-span two-way arch frame (the main arch frame adopts a three-center circular type) cable-membrane structure stockyard closure system, which belongs to the technical field of international patent classification E04B. Background technique [0002] Due to the large accumulation area required for each material, the large space occupied by the conveying and retrieving machine, and no economic benefits, most of the early materials were stacked in the open air, but open air stacking would cause dust pollution. According to research, dust pollution will not only cause a large amount of material loss and huge economic losses, but also have a huge impact on the environment. Taking coal as an example, loading and unloading 1 ton of coal will generate 3.5-6.0 kg of coal dust, and every ton of coal stockpiled will generate 1.5-2....
